vMEANS FOR INCREASING VISIBILITY OF STOCK QUOTATIONl BOARDS `PatentedFeb. 21, 1933 UNITE STATES PATENT- OFFICE ALLISON A; CLOXEY, OFRUTHERFORD, NEW JERSEY, ASSIGNOR T0 INTER-NATIONAL COMMUNICATIONSLABORATORIES, INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK MEANSFOR INCREASING VISIBILITY 0F VSTOCK QUOTAT'ION BOARD-Sy Applicationfiled March 4, 1931.

My invention relates to stock quotation boards and particularly toincreasing the visibility of the signals or indicators of such boards.

In stock quotation boards of the automatic type, provided withindicators or signals for displaying the quotations of the variousstocks, it has been customary to arrange the indicators in rows parallelto the board or wall of the room with the displayed figures also setparallel to the face of the board. This results in the figures displayedby the indicators at the extreme ends of the 'board being illegible toan observer located in the diagonally opposite corner of the room.

This illegibility is due to the sharp angle at which the observer viewsthe indicators, and becomes quite pronounced in the case of large boardslocated in large rooms.

The object of my invention is to increase the visibility of theindicators by tilting or positioning the indicators so that the faces ofthe displayed figures are inclined toward the center of the board. Theindicators are gradually inclined in such a mann-er that the indicatorsmost remote from the center of the board are inclined at the greatestangle to the face of the board.

Arranging the indicators at the proper angle will materially increasethe average visibility of all the indicators.

Various features of my invention will be pointed out in the descriptionto follow. l

Referring to the drawing:

Figure l shows a front view of an indicator;

Figure 2 is a sectional view of Fig. l on line 2-2;

Figure 3 shows a row of indicators arranged in accordance with myinvention.

Referring to Figs. l and 2, the indicator which may be of any standardtype comprises a plurality of number wheels on which, as shown in Fig.1, the numerals 2, 5, 8, 7 and 4 are displayed. The numerals appear inthe openings or windows 2l in the cover or casing 23. The mechanism foroperating the number wheels will not be described7 as it is notnecessary for an understanding of my invention.

Serial No. 520,026.

Referring to Fig. 3,1 have shown a row of indicators or signals markedl1 to 30 inclusive, associated with a board l0, upon which they aremounted. For a Y complete stock quotation board there would be aplurality of such rows, the number being dependent upon the differentstocks to be quoted or displayed.

It will be noted that indicators 11 to 20 are located to the left of thecenter line 60 of the board 10, while indicators 21 to 30 are located tothe right. Beginning with indicators 20 and 21 and ending withindicators 11 and 30, it will be seen that the inclined positionsgradually increase and that the two most remote indicators 1l and 30 areinclined at the greatest angle to the face of the board. The angle ofinclination of the various indicators decreases toward the center of theboard.

Figs. 1 and 2 show the angular position of indicator 14 which isrepresented in the row of Fig. 3.

For illustration, the positions of various observers in the room 50 isindicated at 41, 42, 43, 44 and 45.

It will be noted that the observer at position 42 to the left of theroom has a clear view of the faces of indicators, the angle of visionbeing indicated by the lines extending to indicators 11,20 and 30 whichoccupy, respectively, positions to the extreme left, the center and theeXtreme right of the row.

The observer occupying position 41 in the center of the room likewisehas a clear view of the same indicators.

With this arrangement, the observers at all of the positions indicatedhave a clear view of all indicators and the numerals or characters areclearly legible to all.

What is claimed is:

1. A stock quotation board comprising a plurality of visual signalsarranged in a horizontal row, the signals toward the ends of the rowangularly positioned to incline toward the center of the board, a shieldprovided with a window for each signal, said windoWs occupying angularpositions in accordance with the angular positions of their respectivesignals. i

2. A stock quotation board comprising a plurality of visual signalsarranged in a horizontal row, each of said signals having an angularlinclination in a horizontal plane, a Window for each of said signalsalso having a corresponding angular inclination.

3. A stock quotation board comprising a plurality of visual signalsarranged in a horizontal row, and a Window for each signal having anangular inclination in the horizontal plane, and each signal beingmovable to present an indicating` portion thereof opposite the Windowtherefor'.

4. A stock quotation board comprising a plurality of visual signalsarranged in a horizontal row, a shield provided with a Window for eachsignal, the Windows towards the ends of the row being angularlypositioned to incline toward the center of the board, and the signalsbeing movable to present an indicating portion thereof opposite the`Window therefor.

In Witness whereof, I hereunto subscribe my name this 3rd day of March,1931.
